ATTORNEY PHYSICAL THERAPY DEVICE WITH VERSA'IILE ADJUSTING AND MOUNTINGMEANS The prior art teaches the general concept of mechanical orelectrical devices to impart rotary and/or reciprocating exercisingmotions to various parts of the human body, including to the arms, legs,and proximal portions of the torso. Such prior physical therapy devicesare typically designed to offer relatively vigorous and high-speedmotions to the selected body limbs, an while they are efiicaceous anddesireable for relatively young and healthy individuals, they are toovigorous and grossly inappropriate for the elderly and the more languid.In addition, such prior art devices tend to be bulky, heavy, anddifficult to move from one location to another; thus, they are usuallynecessarily semipennanently maintained in a gymnasium or other specialroom, and hence not conveniently available to less ambulatoryindividuals and practically unavailable to the infirm and the bedridden.Attempts have been made to design less vigorous type exercising machinesspecifically for the feeble and bedridden, but such machines are soonoutgrown by the patient as his physical condition progressivelyimproves.

It is accordingly a general object of the present invention to provide aphysical therapy device for exercising the body limbs and proximal torsoparts for patients at various levels of muscular development, includingfor patients progressing to higher levels of body development andrecovery.

It is another object of the present invention to provide a physicaltherapy device having novel structural adjustment features whereby theexercising device will versatilely accommodate nonnally encounteredranges of body sizes, including for males, females, tall, short, obese,slender, etc.

It is a further object to provide a physical therapy device that isrelatively lightweight and portable, and that can be stably employed ina variety environmental situations, such as in the typical dwellinghome, in hospital rooms, and in physical therapy rooms. Ancillaryobjects include versatilely mounting the device in conjunction with anordinary pivotal door panel, a wall, or a bed in a typical dwelling orelsewhere, or in a typical hospital or nursing home room as adjacent tothe kinds of beds and physical environments customarily encounteredthereat.

Further and related objects include the provision of a physical therapydevice that is light in weight, stable, of economical and unencumberedconstruction, of safe and reliable operation, versatilely amenable tonormally encountered use environments, operatable by most patientswithout the necessity for attendant personnel, and adaptable forprogressive improvements in physical and muscular vigor.

With the above and other objects and advantages in view, which willbecome more apparent as this description proceeds, the physical therapydevice generally comprises: an upright lofty frame or standard, togetherwith novel fastener means for temporarily immovably stationing the loftystandard with respect to an appropriate relatively stationary anchoringmeans, such as a door panel, a wall, a sleeping bed, etc., a poweredrotatable shaft attached to the upright standard and verticallyreciprocatable therealong to a selected height; and elongate arm memberattached to and directly revolvable with the powered revolvable shaft,the arm member extending generally radially from the revolvable shaftand being of adjustably selectable length whereby the verticalcircumscribable path of the arm member outward end is of selectablyvariable radius; and means attachable to said arm member to permitremovable engagement with a patients anatomical limb and for impartingrotary and reciprocating exercising motions thereto.

The primary embodiment D of the physical therapy device will now bedescribed, general reference initially being made to FIGS. 1-3. There isa vertically upright lofty standard or frame 10 extending along avertical axis 11, said upright frame 10 being temporarily immovablystationed with respect to a relatively stationary uprightly extendinganchoring means, e.g. the conventional door panel P" of FIGS. I and 2,the sleeping bed 100 of FIG. 4 etc. A horizontally revolvable shaft 35,powered herein by electric motor 30, is vertically reciprocatablyattached along standard 10, as through shelf 36, whereby shaft 35 has aplurality of selectable fixed elevations along said upright standard.Elongate arm member 40 (having an outward end 41) is attached to anddirectly revolvable with powered shaft 35, said arm member 40 extendinggenerally radially and perpendicularly from shaft 35. Arm member 40 isof adjustable length from shaft 35 whereby the vertically planarcircumscribable circular path of the arm member outward end 41 is ofselectably variable radius. There are means for permitting removableengagement between a patients anatomical limb and arm member 40, such asa horizontal bar, e.g. hand grip 45, revolvably attached to arm member40 at 41. Moreover, bar 45 might carry an elongate flexible member 46terminating as a lower end stirrup 47. Thus, as motor shaft 35 revolvesat a slow angular velocity about its shaft axis 35A, a patient mightmanually grasp handle grip 45 to impart circular exercising motions tothe arms and shoulders, or he might insert his foot or calf throughstirrup 47 to impart similar exercising motions to the legs and hips.

There are important adjustable structural features for physi cal therapydevice D to accommodate patients having a wide range of physicalattributes and anatomical dimensions. For example, the adjustable heightfor powered shaft 35, the adjustable radial length for arm member 40between 35 and 41, and the adjustable length offlexible strap 46, willallow accommodation to the patients precise height, position, andanatomical dimensions. The speed and torque of powered shaft might beselectably varied appropriate to a patients level of anatomical musculardevelopment.

Having now generally described the primary embodiment D" of FIGS 1-3,the same FIGS. will now be described in greater detail. Upright frame orstandard 10 has a lower portion 10A nearer to floor F. Upright standard10 herein comprises a pair of opposed upright poles 12, each having anupper end 12A near the door panel horizontal upper end PA" and having alower end 128 near the door panel horizontal lower end PB." Poles 12 arerigidly maintained in spacedapart parallel relationship with atransversely extending horizontal spacer bar 13 attached to therespective poles, closer to their lower ends 123 than to 12A. Theremovable attachment means of upright standard 10 to the door panelanchoring means P comprises a hook means for the door panel upper edgePA," said hook means herein comprising a three-sided member 15 attachedto the respective poles at 12A. The forward vertical portion of eachhooked member 15 carries a rearwardly extending resiliently compressiblemember such as a rubber cup 16 to abut the upright forward side of doorpanel P" immediately below PA." The rearward vertical portion of eachhooked member 15 carries a forwardly extending threadedly engaged wingscrew 17, there being a resiliently compressible member as felt pad 18on screw 17 for abutting the upright rearward side of door panel 1 andin horizontal alignment with the respective cups 16. Thus, the standardupper end 12A is securely removably attached to the upper portion ofdoor panel P" with members 15-18. The lower portion of each pole 12carries a rearwardly extending rubber cup 19, similar to 16, adapted toabut the upright forward side of door panel P" immediately above PB."The lower end 128 of each pole 12 carries a downwardly extending rubbercup 14, similar to rod 16 and 19, for abutting against a horizontalfloor F, to help stabilize the standard lower end 12B and to keep thedoor panel P" from pivoting at its hinges (not shown).

Door panels, e.g. P," come in a range of heights between the horizontaledges PA" and PB," and to accommodate the exact door panel heightencounted, vertically telescoping poles 12 are preferably employed. Forexample, each pole 12 might comprise an upright lower tubular segment12D extending upwardly from 128 an having an upper terminus 12N below12A; each pole 12 further comprises an upright upper elongate segment12C extending downwardly from 12A into the internal bore of lowersegment 12D. A set screw 1(" threadedly engaged with tubular segment 12Dnear 12N acts as a means to temporarily immobilize the axialrelationship between telescoping members 12C and 12D.

Revolvable shaft 35, extending horizontally forwardly from uprightstandard 10, is herein powered by a slow-speed (1 to 12 r.p.m.)constant-torque electric motor 30. Motor shaft 35 is verticallyreciprocated along upright frame to the desired elevation, as bymounting the motor 30 onto a shelf 36, which is verticallyreciprocatable along 10. Shelf 36 comprises an upright collar portionhaving a pair of parallel upright bores whereby collar 37 is verticallyslidable along the respective tracklike poles 12 of standard 10. Shelf36 further comprises an angular support 38 extending integrallyforwardly from collar portion 37, and motor 30 is attached atop supportportion 38. A pair of setscrews 39 threadedly engaged with collarportion 37 and adapted to abut the respective poles 12 (herein along12D) sets the selected height for revolvable shaft 35 of motor 30. Thereis a wire-grid-type upright safety guard 93 attached to the forward endof the motor housing and interposed between arm member 40 and motor 30,the radius of circular guard 93 exceeding the maximum radial length ofarm member 40 between outward end 41 and shaft 35.

The radially extending length of arm member 40 from revolvable shaft 35to the arm member outward end 41 is herein accomplished by providing alongitudinal slot 42 for arm member 40, shaft 35 passing through slot42. The forward end of shaft 35 carries a hub 32 (attached to 35 withsetscrew 34), said hub 32 including a forward flange 33 abutting therearward side of am member 40 at slot 42. Plate 43 abuts the forwardside of arm member 40 at slot 42. A pair of screws 44, each passingthrough the intervening slot 42 and the members 33 and 43, temporarilysets the selected radial length for arm member 40 between its outwardend 41 and its selected inward end at 35.

Horizontal bar 45, functionable as a handgrip, is revolvably attached toarm member 40 and extends forwardly from its outward end 41. Forexercising the feet, legs, and hips, a flexible elongate annular member46 loops over and extends downwardly from bar 45. A conventional leatherstrap with spaced perforations therealong together with a prong-typebuckle 46A provides desireable adjustable length features. A stirrup 47,adapted to engage the patient's foot or calf, extends downwardly fromthe lower end of flexible elongate member 46.

There is an electrical cord, such as the conventional plug-in type 48,to supply motive power to the electric motor 30. There is a medialswitch 49 along cord 48 and positionable relatively close to bar 45whereby the patient can turn the electric power "on and off." Moreover,there might be a speed control such as rheostat R so that the patientcould control the angular speed of shaft 35, even down to an off or zerolevel. Motor 30 might include a locking means, such as a high resistanceinternal clutch, or as a magnetic brake, to immediately stop the shaft35 and arm member 40 when the switch means, e.g. 49, is deactuated.

It is readily apparent that the primary embodiment of the physicaltherapy device D is readily employable with a stationary wall anchoringmeans, as by use of an elongate horizontal screw (not shown) attachingframe 10 to such wall. Embodiment D" might also be removably anchored toconventional and hospital-type beds. For example, more languid patientsmight be confined to a sleeping bed of the representative type 100 shownin FIG. 4 and typically comprising an upright headboard 101 for the bedtransverse forward head end an inverted U-member 102 at the bedtransverse foot end. Members 101 and 102 are commonly rigidly tiedtogether with a pair of longitudinally extending parallel side rails 105which are substantially L-shaped in transverse cross section. The siderails 105 also serve to horizontally support a box spring 106 which inturn might horizontally support a mattress 107 thereupon. The bed footend might include a transversely extending rigid upright panel 103integrally attached to member 102, and might further include atransversely extending L-shaped foot rail 104 integrally attached tomember 102 below panel 103.

FIGS. 4 and 5 best describe the situation wherein the physical therapydevice D" has the sleeping bed foot end region serving as the anchoringmeans. Lower portions 10A only of the vertical frame 10 are shown, itbeing understood that the rotatable shaft 35 extends forwardly fromframe 10 and from bed foot end 102-104 whereby arm member 40 is abovemattress 107. There is a carriage member 60 vertically reciprocatablyattachable along lower portions 10A of physical therapy device A, saidcarriage 60 herein comprising a pair of upright tubular portions 61slidably surrounding the respective poles 12 of frame 10. The respectivetubular portions 61 are integrally tied together with a pair of rigidspacer bars including an upper spacer bar 62 and a lower spacer bar 63.Each tubular portion 61 is provided with a setscrew 64 adapted to engagea pole 12 (herein along 12D) whereby the vertical height of carriage 60along frame 10 might be selected. A Z-shaped bracket 65 is removablyattached to upper spacer bar 62 with a threaded bolt 66 so that bracket65 extends codirectionally forwardly with shaft 35, and bracket 65 booksover the upper edge of lofty transverse panel 103. A winged bolt 67 isthreadedly engaged with bracket 65, bolt 67 having a compressible pad 68to abut the forward upright surface of panel 103, the rearward uprightsurface of 103 abutting carriage 60. Thus, the combination of bracket 65securely attached to the lofty upper edge of panel 103 together withfloor abutments 14 provides a secure anchoring means for physicaltherapy device D.

FIGS, 6 and 7 best describe the situation wherein the physical therapydevice D" has one of the sleeping bed side rails 105 serving as ananchoring means. Carriage 60 is employed with tubular portions 61slidably surrounding the respective poles l2 (herein along 12D) belowside rail 105. However, 2- shaped bracket 65 is replaced by an L-shapedfoot rest member 74 having a vertical leg 75V, a horizontal leg 75H(extending codirectional with shaft 35), and a diagonal brace portion758. Foot rest vertical leg 75V is provided with a vertical slot 76 forpassage of bolt 66 through slot 76 and spacer bar 62 whereby foot rest75 is positionable at the desired elevation. There is a pad 77, similarto pads 14, extending downwardly from horizontal leg 75H to abut thefloor immediately below box springs 106.

Attachment means at the bed rail 105 includes a pair of upright angularplates 85, each angular plat being provided with a angular bed 86 topartially surround bed rail 105. The two ends of each angular plate 85are removably attached to a vertical bar 82 with a pair of bolts 83, thetwo vertical bars 82 being tied together with horizontal spacer bars 81.Vertical bars 82 abut the forward side of the respective poles 12 andare vertically reciprocatably attached to poles 12 as by pivotal bars 84on the rearward side of poles 12. The vertical bars 82 are temporarilysecured at a desired height along poles 12 (appropriate to the height ofbed rail 105) as by two bolts 89 along axis 11. Each bolt 89 extendsfrom a spacer bar 81 to a pivotal bar 84. Each pivotal bar abuts therearward side of both poles 12. Thus, the foot rest 75 supplements theattachment to relatively low anchoring means (lower than panel 103), andstably supports the lofty center of gravity for device dlD.7

Thus, it can be seen that the physical therapy device is amenable to aplurality of normally encountered anchoring means, is of adjustableheight as along frame 10, is adjustably adaptable to various anatomicalendowments and conditions as through controlled motor speeds and armmember radii, and appropriate to various anatomical limb regions.

From the foregoing, the construction and operation of the physicaltherapy device will be readily understood and further explanation isbelieved to be unneccessary. However, since numerous modifications andchanges will readily occur to those skilled in the art, it is notdesired to limit the invention to the exact construction shown anddescribed, and accordingly, all suitable modifications and equivalentsmay be resorted to, falling within the scope of the appended claims.
